Uncle Sam prints the money, so how can the US be going broke?

I can’t see how the US can be going broke unable to pay its debts? How can it even have debts? It taxes the people near death, it was able to crap money out the wazoo for a decade to pay for an illegal war and an ill-thought out one. Who does the US owe money to? The US sure doesn’t act as if it owes me a dime. Oops, that dime devalued down to seven cents while I was posting.
